A face humana do complexo industrial da CU.F. : Um património a preservar

Tendo por base o contexto histórico e patrimonial no qual se desenvolveu o interesse pelo património industrial em Portugal, a partir do último quartel do século passado, este trabalho procura ser um contributo para a valorização histórica e patrimonial de um espaço industrial de grandes dimensões como foi o caso do Complexo Industrial da C.U.F. no Barreiro. O trabalho estrutura-se em duas partes, na primeira parte abordamos o tema Património Industrial na sua génese e enquadramento histórico como conceito e suas perspetivas de preservação e valorização; seguidamente faremos uma pequena síntese histórica do Barreiro até ao Complexo Industrial da C.U.F., onde abordaremos também o aumento populacional e o crescimento urbano, passando pelo problema da habitação e o surgimento dos Bairros Operários até aos espaços de lazer e catividades culturais ligadas ao Operariado, não esquecendo as estruturas de saúde, assistência, lazer e as politicas sociais. Na segunda parte abordaremos a importância de valorizar o património industrial e consequentemente o Complexo Industrial com a proposta de um programa de valorização do mesmo, através da criação de núcleos museológicos e de um roteiro de Património Industrial. ABSTRACT: The Human Facet of the Industrial Complex of C.U.F.- a Heritage to Preserve The foundation of this Project is the historical heritage for which developed the interest in Portugal's industrial heritage from the last quarter of the past century. This project has the intention to contribute to the historical and heritage valorization of one of the biggest industrial complexes, which was the case of the Industrial Complex C.U.F. in Barreiro. This project has two parts, the first part will be about defining the theme of industrial heritage and its genesis and the historical setting as a concept and its perspectives of preservation and valorization; afterwards, we will do a small historical synopsis of Barreiro including the Industrial Complex of C.U.F., where we will also refer to the increase in population growth and the urban development, followed by the housing problem and consequently the increase of working class neighborhoods, even to the prices of leisure and culture activities related to the working class, not forgetting the health structures, assistance, leisure and social politics. ln the second part, we will also talk about the importance of valorizing industrial heritage, and subsequently the Industrial Complex, with a proposal of a valorization programme of the Complex with the creation of a museological core as well as an industrial heritage guide.

As sociedades de capital de risco em Portugal: Critérios adoptados no processo de tomada de decisão de investimento

Este estudo procura compreender a importância atribuída aos critérios utilizados pelas SCR portuguesas, na seleção e avaliação de projetos do tipo early-stage. Os dados utilizados foram recolhidos com recurso a questionário aplicado a 22 SCR portuguesas. Foram utilizadas técnicas de estatística descritiva, testes não paramétricos e análise de clusters. Concluiu-se que a personalidade e experiência do empreendedor e equipa de gestão são os critérios mais valorizados. As SCR com capital maioritariamente privado consideram mais importante o grupo de critérios relativo à personalidade do empreendedor e equipa de gestão do que as de capital maioritariamente público; e, as SCR que ainda não se internacionalizaram, consideram mais importantes o grupo de critérios relativos à personalidade do empreendedor e equipa de gestão e o grupo de critérios relativo aos aspetos financeiros, do que as SCR que se internacionalizaram. Na análise de clusters identificaram-se três grupos de SCR: Criadores de riqueza de forma sustentada; Monopolistas Impacientes; e, Ciumento. ABSTRACT: This study seeks to understand the relevance of the criteria used by the Portuguese VCs to select and assess early stage type projects. The data used for the study was collected through a questionnaire answered by 22 Portuguese VCs. We employed descriptive statistic techniques, non-parametric tests and cluster analysis. The conclusion of the study was that the personality and experience of an entrepreneur and of the management team are the most valued criteria. VCs with a majority of private share capital found the group of criteria related to the personality of the entrepreneur and of the management team to be more important than the companies with a majority of public share capital; additionally, the VCs that have not yet expanded internationally, consider the personality of the entrepreneur and management team and the group of criteria associated to financial aspects, to be more important than the VCs that have already expanded abroad. Throughout the study of the clusters we were able to identify three VCs groups: Creators of sustained wealth; Impatient Monopolists and Jealous.

Análisis de la dimensión fractal del género Quercus en el sur de Italia

En estudios anteriores propusimos un nuevo método para el estudio del género Quercus (Musarella et al., 2013), baseado en la dimensión fractal (DF). En este trabajo analizamos la DF del género Quercus en el sur de Italia, para ello utilizamos hojas de árboles pertenecientes a Q. robur subsp. brutia, Q. cerris, Q. congesta, Q. crenata, Q. ilex, Q. suber, Q. virginiana. De cada árbol se toman hojas de cada uno de los puntos cardinales para complejiada de la estructura morfológica de las hojas. Este análisis extrae información sobre los caracteres fenotípicos de las hojas utilizadas, tales como el número y morfologia de los nervios, ángulos nervios secundarios con principal, contorno de hojas, aspecto reticulado de la hoja etc. En nuestro análisis, no se han detectado diferencias significativas entre la DF en cada una de la orientaciones y la DF global para cada una de las especies. En este trabajo corroboramos estudios anteriores realizados por los autores, en los que se proponía una DF < 1,6 para Quercus esclerófilos y DF entre dos especies sea cero o su cociente sea uno, el grado de parentesco entre las dos especies es del 100%; DFA - DFB = 0; DFA/DFB = 1, la especie Ay B son iguales; por ello cuanto menor es la diferencia o bien cuanto más se acerque el cociente a 1, mayor es la semejanza entre las especies. Si este cociente tiene un valor alejado de 1 como ocurre entre vfvi/vfsu>2, las especies Q. virginiana y Q. suber están muy distantes entre sí. Además, la realización del Test de Rango Múltiple, que es un procedimiento de comparación para determinar cuáles medias son significativamente diferentes unas de otras, confirma los resultados obtenidos de la forma anteriormente expuesta. Conto et al. (2007) ponen de manifiesto el origen hibridógeno de Q. crenata, y según el análisis molecular existe una mayor similitud genética entre Q. crenata y Q. cerris, que entre Q. crenata y Q. suber. Los DF de Q. crenata 1,868; Q. cerris 1,677 y Q. suber 0,932; siendo DFQsu 0,745 y DFQsu = 1,8, lo que significa que existe gran diferencia fenotípica (genética) entre los parentales, se presenta una mayor semejanza entre Q. crenata y Q. cerris que entre Q. crenata y Q. suber, ya que la diferencia DFQcr-DFQce = 0,191 y DFQcr/DFQce = 1,1, por lo que tienen un fuerte grado de semejanza, mientras que DFQcr-DFQsu = 0,936 y DFQcr/DFQsu > 2, lo que pone de manifiesto las fuertes diferencias fenotípicas entre el híbrido y el parental.

Phytosociological survey on the Lusitan-Extremadurean grasslands of Dactylis hispanica subsp. lusitanica (Stebbins & D.Zohary) Rivas-Mart. & Izco

Deeply connected with forest serial dynamics, and present in almost semi-natural landscapes of Iberian Peninsula, Dactylis hispanica subsp. lusitanica perennial grasslands antalis a major issue on biogeographical analysis, once it lacks on syntaxonomical solutions for its affiliation and respective positioning on serial dynamics of distinct territories, which edaphoclimatic envelopes suggest different floristic assemblages. Mainly part of Agrostion castellanae-Stipion giganteae alliance, the Lusitan-Extremadurean grasslands were studied, with the objective of updating that biogeographic Province, and several phytosociological relevés were made, allowing the syntaxonomical update as well to resolve the serial-dynamics arrangement where this peculiar grasslands makes part of. At last this communities belong to priority 6220 [*Pseudo-stepe with grasses and annuals (Thero-Brachypodietea)], habitat that interests as well for conservational matters, due to its peculiar flora.

Vegetation series as a basis for habitats and species conservation: methodological aspects

Vegetation series, defined as the sequence of stages in a sucession, and know as sigmetum (synassociation), describes the set of plant communities or stages that can be found in similar tesselar spaces as a result of the sucession process. This establishes the concept of vegetation series; a climatophilous series is one that depends on the climate, whereas an edaphoxerophilous series depends on the dryness of the soil, and is found on crests, spurs, ledges and limestone and siliceous rock fields. Edaphohygrophilous series are located in valleys, dry water courses and river terraces, and depend on the water present in the soil, which may become temporarily flooded and thus condition the temporihygrophilous series; they represent the transition between the clearly edaphohygrophilous and climatophilous series. The vegetation permaseries represents the perennial communities of permatesselae or similar permatesselar complexes, as occurs in polar territories, hyperdesert, high-mountain peaks, and non-stratified communities lacking in serial communities. The edaphoxerophilous series may include -in addition to the series head- permaseries (permanent communities) and other habitats, such as annual and crevice habitats. A territory behaves undergoes soil-loss phenomena it may become an edaphoseries, if the loss of the soil factor produces a situation of rocky crest. Thus the edaphoseries may act as dynamic transitional stage between the climatophilous series and the permaseries.

Brèves considérations sur Jean-Marie Géhu et la phytosociologie au Portugal

O artigo destaca a importância do Prof. Jean-Marie Géhu no desenvolvimento da fitossociologia, não só através do incentivo e apoio à fundação de várias associações científicas, mas também através da criação de três séries de periódicos científicos, com larga difusão na Europa. Por outro lado, destaca ainda a forte ligação do Prof. Jean-Marie Géhu a Portugal, onde orientou trabalhos de doutoramento e realizou vários levantamentos de campo que deram origem a publicações científicas estruturantes para a Fitossociologia em Portugal. Por último, em estreita colaboração com outros fitossociólogos europeus, saliente-se ainda a elevada produção científica que em muito contribuiu para o desenvolvimento desta ciência.

RELAZIONE TRA IL CONSUMO DI OLIO EXTRAVERGINE DI OLIVA E I CASI DI DECESSO PER MALATTIA DI ALZHEIMER IN SPAGNA

In the chemical composition of olive oil (Olea europaea L.) it is emphasized the massive presence of oleic acid (over 70%), monounsaturated fatty acid part of the family of omega 9, a 7-8% linoleic acid (omega 6) and a small presence (0.5-1%) of linolenic acid (omega 3). For its high content of monounsaturated fatty acids, olive oil is the most stable and therefore the most suitable for heating, compared to oils with a dominance of polyunsaturated fatty acids. Interest in vitamin E has increased in recent years, thanks to its high antioxidant power and its role against related diseases with age-related, visual, dermatological, cardiovascular disorders Alzheimer’s disease and more. Vegetable oils are a major source of vitamin E through diet (Sayago et al., 2007), especially with the variety of olives “Hojiblanca”. Thanks to unsaturated fatty acids cell oxidation can be prevented: this helps prevent many illness, and even premature aging. So far, the advantages acknowledged to olive oil are those of lowering cholesterol, preventing cardiovascular disease, diabetes and cancer. Among the most recent researches it is important to distinguish the studies carried out on their contribution to the prevention and treatment of breast cancer and Alzheimer’s disease. Researchers found that in addition to the benefi ts that give monounsaturated fats, in extra virgin olive oil, there is a substance called “oleocanthal”, which helps protect nerve cells damaged in Alzheimer’s disease. The importance of this discovery is enormous when one considers that only Alzheimer’s disease affects 30 million people around the world, with a different distribution depending on the type of oil in the diet (Olguín Cordero, 2012). The latest research endorses that oleocanthal works by destroying cancer cells without affecting the healthy ones, as it is stated in the Molecular and Cellular Oncology Journal. Studies carried out in different Spanish universities have concluded that thanks to the antioxidant power of olive oil, a disease such as Alzheimer can be prevented. In conclusion, we can say that the Mediterranean diet rich in extra virgin olive oil greatly infl uences on human health, reducing, delaying or even eliminating several diseases.
